Yes....insulin has a prominenet effect on adipocytes by which they get glucose into them. The glucose once inside is again converted into fat. The whole mechanism actually depends on a glucose transporter protein GLUT 4 present specifically on fat cells. Gluconeogenesis occurs in normal course but i...

Mitochondria don't divide into halves and get into new cells. They have their own set of genes to function...are semi-autonomous. They even have different immune system recognition system which is in may terms related to bacteria. During normal cell division, there may also be duplication and then s...

Schwan cells produce myelin sheath but are found in peripheral neurons only, the neurons of CNS are derived from Oligodendrocytes. I hope it's a bit clear now.

Re: fatty acid synthesis

Kindly have a look at the points....

1) Fatty Acid Synthase (FAS) enzyme is different in prokaryotes and eukaryotes.
2) Length of fatty acid differs
3) Site of synthesis is different (SER in major eukaryotes)
4) Transcription factors and many other genes regulate differently in both.
